Don’t forget to take transportation cost out of your $3000 per month.

I live across the street from the office and yes the rent is stupid, but my commute is a 5 minute walk.

And rent is still stupid in a 30min radius (for a total of 1h/day). You really have to go 1h+ radius to make a significant dent in rent around here (SF).

I did - $500 a month. I have no idea what communitng costs, and little idea about rent.

I have a 5 second commute from the bedroom to the office (3 minutes if I go downstairs and boil the kettle first), far easier. Monthly Mortgage is less than the weekly rent that one colleague pays in London, and he still has a 45 minute commute each way.

If you are working for somebody else, you can't exactly make any extra money by working extra hours. At least in a programmers case.

The only real thing to gain in this case is convenience.

I work full time in software engineering and do occasional paid freelancing work. It's quite possible to be full time and work extra.

Depends on your contract and whether you get paid overtime.
